Hit Control+O to save then Control+X to exit nano. Step 15 – You’ll also need to enable IP forwarding in the file /etc/nf. Step 14 – Lets start OpenVPN service on your server for the very first time: 1 #plugin /etc/openvpn/radiusplugin.so /etc/openvpn/radiusplugin.cnf #- Uncomment this line if you are using FreeRADIUS Plugin /usr/share/openvpn/plugin/lib/openvpn-auth-pam.so /etc/pam.d/login #- Comment this line if you are using FreeRADIUS Key /etc/openvpn/easy-rsa/2.0/keys/server.keyĭh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem Step 13 – Now enter this value in that config file:Ĭert /etc/openvpn/easy-rsa/2.0/keys/server.crt Step 11 – Now issue command below to build Diffie Hellman: 1 The only 2 required are sign the certificate (choose “y”) and 1 out of 1 certificate requests (choose “y”) Step 9 – It’s time to build necessary CA file: 1 Step 8 – Create the certificate using these commands: Once done hit Control+O to save then Control+X to exit. Step 6 – Copy the easy-rsa folder to /etc/openvpn/, use this command: 1Ĭp -R /usr/share/doc/openvpn-2.2.2/easy-rsa/ /etc/openvpn/Įxport KEY_CONFIG=’$EASY_RSA/whichopensslcnf $EASY_RSA’Įxport KEY_CONFIG=/etc/openvpn/easy-rsa/2.0/openssl-1.0.0.cnf Step 5 – Issue the special yum command: 1 Step 4 – Then build the rpm package using this command: Otherwise if you see “ i686 i386 GNU/Linux” or “ x86 GNU/Linux” means your machine is 32-bit. If you see “ x86_64 GNU/Linux” at the end of the output line means your server is 64-bit. How to know which one is your server? Issue this command: 1 Step 3 – Now add correct repo for your server: Step 2 – Now download LZO RPM and Configure RPMForge Repo. Yum install gcc make rpm-build autoconf.noarch zlib-devel pam-devel openssl-devel -y Step 1 – Now issue this first command syntax: 1 Please enable TUN/TAP options in your VPS control panel (e.g: SolusVM). It exists to provide a free enterprise class computing platform and strives to maintain 100% binary compatibility with its upstream distribution. a community- supported,mainly free software operating system based on Red Hat Enterprise Linux. Commercial support is offered via a number of vendors. In turn the core developers are supported by an active user community including system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.ĬentOS has numerous advantages over some of the other clone projects including: an active and growing user community, quickly rebuilt, tested, and QA’ed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ. CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible developed by a small but growing team of core developers. Otherwise, large packets cannot be fragmented and service failures may occur.A brief introduction to CentOS, or if you are a restless soul, just go straight to the process.ĬentOS stands for Community ENTerprise Operating System.ĬentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor. If the CRS1 and Huawei devices are interconnected through Ethernet interfaces in an MPLS VPN, the Ethernet interface MTU on the CRS1 must be greater than or equal to 1522. For example, if the MTU on Ethernet interfaces of the CRS1 is changed to 1518, then the MTU on Huawei devices needs to be changed to 1504 accordingly.Ģ. Otherwise, the ISIS neighbors will never be Up. Any change to the MTUs should be based on 15. The default MTU 1514 on Ethernet interfaces of the CRS1 corresponds to the MTU 1500 on Ethernet interfaces of Huawei devices. The IS-IS protocol is run on the Ethernet interface between the CRS1 and a Huawei router and Small-hello is not configured, the interface sends a Hello packet according to the MTU. The default MTU on the Ethernet interfaces of Huawei routers is 1500 bytes, which include only the packet payload.ġ. The default MTU on all Ethernet interfaces of the CRS1 is 1514 bytes, which include an Ethernet frame header and packet payload. The default MTU on all Ethernet interfaces of the routers (including 120xx, 100xx, 76xx, and 65xx) of the company is 1500 bytes, which include only the payload of packets. Special attention should be paid to the change of the default Ethernet interface MTU. The software system and default configurations of the CRS1 are greatly different from those of the legacy routers such as 120xx, 100xx, 76xx, and 65xx. The CRS1 is a TB router launched by Manufacturer C in 2007.
